"The way aminopyralid works in plant material, it is very likely the effects you describe are a result of residues being retained in daughter tubers of potatoes grown last year. Is it only these “groundkeepers”, the tubers that were accidentally left in the soil over winter, that are showing symptoms, or are other plants of different species also affected? If it is only the potatoes, I doubt the affects are as a result of manure in the soil still containing aminopyralid.
Broadly-speaking, any manure that was dug-in last year, and has been well dug over since, should have had any remaining residue of aminopyralid broken down by soil micro-organisms. This is dependent on the plant material having broken down, allowing the microbes to work directly on the aminopyralid. However, if plant cellulose material is still easily found in the soil there could still be a problem in 2009".
As yet the dahlias planted in the same area are growing without any ill effect.
If you were affected last year and can give an update of the situation in your garden/plot now or have any advice that may help those affected this year then please post a comment or email me and I will add anything useful to this web page.

Amongst other things this has been a tomato planting week. In the garden greenhouse we are trying our tomatoes in large grow bags using the ring culture system. This is supposed to give the root system more depth of soil in which to develop and is also supposed to help reduce the soggy compost syndrome that can affect growbags.
The rings can be purchased from Harrod Horticultural click here
In the plot green house the tomatoes are planted directly into borders which have been refreshed with bags of compost.It will be interesting to compare the results - that is as long as the dreaded blight, that affected our plot greenhouse last year, doesn't treat us to a repeat performance.

Each time we have ventured to the plot we have been rained off. On Sunday I managed to mulch 3 strawberry plants with straw and then the heavens opened and the rain set in for the rest of the afternoon.

The wind was far less welcome with some plants especially the cardoons suffering from the battering that it gave them. The broad beans plants are now leaning westwards. Hopefully a period of calm weather will see them right themselves.
By the way the hawthorn – May blossom is now out and so we can officially start to cast our clouts. The only problem is that at the moment they are cast they seem to need putting back on again!
